Abstract
A process for producing cultures of Gliocladium virens for use as biocontrol agents wherein the production of viridiol is inhibited. Cells of Gliocladium virens are grown in a culture medium and under conditions effective to produce gliotoxin and/or gliovirin, wherein the culture medium includes an amount of a fungicidal steroid inhibitor which is effective to inhibit production of viridiol but which does not substantially inhibit the growth of G. virens. Following recovery, the resultant culture may be used as a biocontrol agent for the control of plant diseases by application to the locus of a plant, seedling or seed to be protected. Coating seeds with the biocontrol agent prior to planting has been found to be particularly effective for the control of soilborne root or seedling diseases.
